Detective Kien: The Headless Horror is a Vietnamese period folk horror mystery set during the Nguyen Dynasty, following a detective who unravels apparent supernatural killings in a rural village. Directed by Victor Vu, the film adapts a local literary source with an all-Vietnamese cast and a historical setting that keeps cultural identity firmly intact. The Neutral label reflects a largely clean slate: no progressive social messaging, no traditional values agenda, no religious friction, and no identity-politics framing of any kind. The story's resolution trades ghost stories for human culpability and village power struggles, which is a classically rational detective move that manages to be neither conservative nor liberal about it.
